Özet

NHC-Pd-PPh3 complexes with the bulky benzyladamantyl substited N-heterocyclic carbene (NHC) were synthesized and characterised by NMR, HRMS and micro analyse. These complexes were proceeded to Sonogashira-Hagihara coupling reaction between aryl bromides and phenylacatylene in DMF. All palladium compounds are stable and have high catalytic activity on Sonogashira-Hagihara reaction by low catalyst loading. (C) 2017 Elsevier B.V. All rights reserved.
